As one of its daily deals, TigerDirect offers the factory-refurbished Uniden DECT 6.0 3-Handset Digital Cordless Phone System, model no. D1484-3, for $29.99. This $10 mail-in rebate cuts it to $19.99. With around $4 for shipping, that's $11 under the lowest total price we could find for an open-box unit, although we saw a refurb with no rebate hassles for $4 less in December. This phone uses DECT 6.0 (1.9GHz) technology, which reduces interference with 2.4GHz devices, like wireless networks. It features caller ID, wall waiting, digital answering system, and more. A 1-month Uniden warranty applies. Deal ends today.
